Soelve

Soelve was a Geatish sea-king from Jutland who reigned as king of the Swedes for eleven days in 600, succeeding Eysteinn and preceding Ingvar. Soelve trapped the Swedish king Eysteinn and his allies in a banquet hall as they dined, and Soelve burned down the hall, killing all inside. Soelve asked for the Swedes to accept him as king, but Eysteinn's son Ingvar fought Soelve for eleven days before slaying him in battle.
